A Cook's Sunday in Paris

I will be in Paris for just 15 hours on August 31. I am going on a cruise that stops in Le Havre and I am planning to make the trip into Paris.

I've been to Paris once before and would like to focus this trip around food, particularly cooking and markets. I am worried about the time going by so quickly. Since I don't speak French, I'm worried about losing my way and missing things.

I'm thinking about hiring my own tour guide to show me around on a specialized tour like this. Does that seem like a good idea? Any recommendations on guides?

I wanted to let you know that in the end, I met Julien, a food blogger and writer from http://www.julotlespinceaux.com for our Paris food tour. He was a gracious host -- who met us at the Eiffel Tour with croissants to kick off the day. He took us to a market, bakery, cheese shop, wine shop. He had lots of information and ideas about the real cook's Paris. I highly recommend him and am so glad I found him on this board.

on sundays, you should check out the market at the bastille.another idea for a guide is through context tours: http://www.contexttravel.com/paris/they have a lot of private tours they can arrange - i work for them (not doing the food tours, though), and they have a lot of great guides.
